lying Hutchinson Quarry beds are members of a younger 

 series. 



(2.) That the Awamoa and Hutchinson Quarry beds are 

 the upper and lower members of the same series, and lie 

 below the Waitaki Stone and above the Oamaru building- 

 stone. 



(3.) That the Hampden, Awamoa, Waihao Forks, Pareora, 

 and Kakahu beds belong to the Oamaru series. 



(i.) That Captain Hutton was right in separating the Mota- 

 nau beds from the Pareoras. 



(5.) That the Motanau beds overlie the Oamaru series 

 unconformably. 



(6.) That the Geological Survey is right in placing the 

 Kakahu, Waihao Forks, Black Point, and Hampden beds 

 below the Waitaki Stone, but wrong in ascribing the Pareora, 

 Mount Harris, and Awamoa beds to a position above the Wai- 

 taki Stone, and wrong in correlating the Motanau and Pareora 

 beds. 



(7.) That the Pareora fauna is only found in beds under- 

 lying the Waitaki Stone. 



(8.) That nowhere in Otago or Canterbury are beds con- 

 taining the Pareora fauna to be seen overlying the Oamaru 

 series. 



(9.) That there are two horizons of littoral shells in the 

 Oamaru series — namely, the Awamoas, lying above the 

 Hutchinson Quarry beds, and the Waihao Forks beds, over- 

 lying the coal. 



(10.) That the Oamaru series at Weka Pass rests uncon- 

 formably upon the Weka Pass Stone. 



(11.) That the Weka Pass Stone is conformable to the 

 Amuri limestone, and is the closing member of the Waipara 

 series in Canterbury. 



(12.) That the Motanau and Awatere beds belong to the 

 Te Aute series of Older Pliocene age. 



Grouping the beds in the order of their superposition and 

 according to their relationships, we get the following table of 

 formations : —
